I'm with you, guys. I've never heard of "shakers". I checked online and found that "shake" is marijuana laced with powder cocaine. A "shaker" is one of the items needed to freebase cocaine (i.e., shaker/baker/water) which are a shaker bottle, baking powder and water. I got this from a drug dictionary on noslang.com. It says nothing about dilaudid as "shakers". Sorry 285champ. Here on DC, we don't do well with slang terms for drugs. We prefer name brand or generic, rather than "street" terms. Maybe you just thought that "shakers" was "dilodid" (?). Best of luck.
